3. Plug the other end of the CAN
communication cable to the CAN connector on
BMS. Tighten the screw cap at the end of the
cable.
2. There's a protect cap for the CAN connector
on BMS, unscrew the cap.
The wire order of the communication cable is the same as RS485

Connecting Ground Wire
For one battery module:
Unscrew the ground terminal with hexagon wrench on BMS and battery module
at either side of the ground port as marked at the following figure. Connect the
ground wire from BMS to battery module.
Note: 10AWG ground wire is required for grounding.
CAUTION!
GND connection is mandatory!
For 2~4 battery modulles:
The GND connection between BMS and battery module is the same as
described above.
The terminal point for GND connection between battery modules are circled in
red bellow:
